Explanation:

Uppercase B is the brown eyed gene. It's dominant over the recessive gene lowercase b, which is for blue eyes. Convention has the uppercase letter always dominate over the lowercase recessive gene.

Note the genotypes of the offspring are all Bb. This tells us we have nothing but brown eye offspring. The visual indicator also shows four brown eyes, which backs up each Bb genotype. The phenotype is the observed brown eyes that others can see, while the genotype deals with the gene pairings.

Since four offspring out of four total have brown eyes, this means the percent of brown-eyed offspring is 4/4 = 1.00 = 100%

Answer: ELECTRICAL ENERGY to CHEMICAL ENERGY to SOUND ENERGY.

Explanation:

There are laws governing the conservation of energy in physics. The first law of thermodynamics states that in a closed system, energy can neither be created nor destroyed during transformation. With this, the total energy of a given system always remains constant.

This first law of thermodynamics which arouse from special relativity, says that changes in the energy of systems will also coincide with changes in a measure of its energy content.

The ELECTRICAL energy from the outlet charger is transformed and stored as CHEMICAL energy in the battery of the phone. This in turn is converted to SOUND energy when the phone rings.

Radioactive Dating

Explanation:

To get the age range of rocks or fossils, researchers usually make use of radiometric dating technique which is also called radioactive dating. Now, this radioactive dating is based on the principle of comparison between the abundance that's observed from a naturally occurring radioactive isotope including its decay products, with the use of known decay rates.

Correct question is;

A thermal tap used in a certain apparatus consists of a silica rod which fits tightly inside an aluminium tube whose internal diameter is 8mm at 0°C.When the temperature is raised ,the fits is no longer exact. Calculate what change in temperature is necessary to produce a channel whose cross-sectional is equal to that of the tube of 1mm. (linear expansivity of silica = 8 × 10^(-6) /K and linear expansivity of aluminium = 26 × 10^(-6) /K).

Answer:

ΔT = 268.67K

Explanation:

We are given;

d1 = 8mm

d2 = 1mm

At standard temperature and pressure conditions, the temperature is 273K.

Thus; Initial temperature; T1 = 273K,

Using the combined gas law, we have;

P1×V1/T1 = P2×V2/T2

The pressure is constant and so P1 = P2. They will cancel out in the combined gas law to give:

V1/T1 = V2/T2

Now, volume of the tube is given by the formula;V = Area × height = Ah

Thus;

V1 = (πd1²/4)h

V2 = (π(d2)²/4)h

Thus;

(πd1²/4)h/T1 = (π(d2)²/4)h/T2

π, h and 4 will cancel out to give;

d1²/T1 = (d2)²/T2

T2 = ((d2)² × T1)/d1²

T2 = (1² × T1)/8²

T2 = 273/64

T2 = 4.23K

Therefore, Change in temperature is; ΔT = T2 - T1

ΔT = 273 - 4.23

ΔT = 268.67K

Thus, the temperature decreased to 268.67K

Answer:

85.8 m/s

Explanation:

speed=wavelength multiply by frequency

[tex]0.39 \times 220 [/tex]

[tex]85.8[/tex]

Explanation:

Given parameters:

Frequency  = 12Hz

Unknown:

a. Period of its rotation

b. Time required to complete 86 rotations

Solution:

Frequency is the number of times of rotation per unit of time.

  Frequency  = [tex]\frac{n}{t}[/tex]  

Period is the opposite of frequency;

          Period = [tex]\frac{1}{12}[/tex]   = 0.083s

b. Time for 86 rotations;

          Since frequency  = [tex]\frac{n}{t}[/tex]  

n is the number of rotation

t is the time

             t  = [tex]\frac{n}{Frequency}[/tex]  = [tex]\frac{86}{12}[/tex]   = 7.2s

The period of rotation is 1/12 seconds and it takes 7.17 seconds to complete 86 rotations.

Time period (T) in a rotational or periodic motion is defined as the time taken to complete one rotation and frequency (f) is the reciprocal of time period.

                         f = 1/T   ⇒  T = 1/f  , given  that f = 12 Hz

                          T = 1/12 s is the time period of ne rotation

Now if time takes to complete one rotation is 1/12s , then to complete 86 rotation, the time required is

                               t = 86×(1/12) = 7.17 seconds is taken to complete 86 rotations.

Answer:

Explanation:

I got it right

There's a constant force of 35 N exerted on the object of mass 2.0 kg, so it undergoes an acceleration a of

35 N = (2.0 kg) a   →   a = 17.5 m/s²

The object travels 8.0 m, so that it attains a velocity v of

v ² = 2 (17.5 m/s²) (8.0 m)   →   v ≈ 16.73 m/s ≈ 17 m/s

The velocity of the 2 Kg object which travels 8 m along the horizontal frictionless surface is 17 m/s

a = F / m

a = 35 / 2

a = 17.5 m/s²

v² = u² + 2as

v² = 0² + (2 × 17.5 × 8)

v² = 280

Take the square root of both side

v = √280

v = 17 m/s
